The valve trombone emerged concurrently with the invention of valves in the early 19th century. Most early instruments retained the shape and form of the slide trombone, employing three valves with the tubing arranged in place of the slide; others used the new valve mechanism as an opportunity to explore different configurations while retaining the overall cylindrical bore and bell profile.
Hagmann valve, in default (A) and engaged (B) positions, top (above) and side view (below). 1. air flow, from mouthpiece; 2. air flow, to bell; 3. air flow to and from valve tubing; 4. valve casing; 5. valve cap; 6. straight-path valve port; 7. valve ports, to tubing emerging at the top of the valve casing; 8. spindle axis of rotation.
The valve trombone is an exception, using three valves similar to those on a trumpet, and the superbone has valves and a slide. The word "trombone" derives from Italian tromba (trumpet) and -one (a suffix meaning "large"), so the name means "large trumpet".
Thayer axial flow valve on a tenor trombone. The axial flow valve, or Thayer valve, is a brass instrument valve design patented in 1978 by Orla Ed Thayer. [1] Designed with assistance from Zigmant Kanstul, it was originally intended to replace the traditional rotary valve on the French horn, but instead revolutionized the design of trombone valve attachments. [2]
The first of these types was the Stölzel valve, bearing the name of its inventor Heinrich Stölzel, who first applied these valves to the French horn in 1814. Until that point, there had been no successful valve design, and horn players had to stop off the bell of the instrument, greatly compromising tone quality to achieve a partial chromatic scale.

The Superbone can be played as a slide trombone, a valve trombone, or in combination. Using the slide and valves in combination requires the slide positions to be adjusted, just as when using the trigger of an F attachment on a tenor or bass trombone. Using the slide with the first and third valves engaged has the same effect as using an F ...
